I recently completed a basic backend development course and even built some projects for my portfolio. I wasn't expecting much when I applied for a junior backend developer position, mainly just to practice my interview skills. To my surprise, I nailed their take-home API challenge, impressed during the interviews, and got an offer—starting Monday! The issue is, I looked over their tech stack and I only recognize around 40% of it. They use Kubernetes, which I've only heard of but never worked with, and they talked about distributed systems and event-driven architecture during the interviews. My course didn't cover these topics at all. Now I'm freaking out! Should I be honest and risk losing the job, attempt to cram all weekend to learn Kubernetes, show up Monday and pretend I know what I'm doing, or just quit to avoid embarrassment? Is this feeling normal? Do people really bluff their way into these jobs and figure it out later?

Don't stress too much! You got hired because they see potential in you. Nobody shows up knowing everything on day one. Just take it one step at a time: spend a few days getting to know the codebase, then focus on one technology at a time, like Kubernetes or the event-driven stuff. Try using resources like Bootcamp or Codecademy to get hands-on experience. Learning on the job is how most people progress!
Hey, just show up and be ready to learn! Most junior positions come with that kind of uncertainty. Everyone starts somewhere, and you’ll probably find that a lot of new hires feel the same way at first.
Haha, that makes me feel better! I thought I was the only one panicking all weekend. Thanks for the reassurance!

Thanks for the tips! I think I was just overthinking it. Sounds like a manageable plan.
